HOT Jazz pickup - please help identify

I have a pickup which is at least 8yrs old because i bought it used about 7-8 yrs ago. It has large pole pieces and measures 14.25 ohms. It has one small hole in the middle and two small holes on one side. The copper winding is protected by a black fabric covering or tape of some sort. Does anyone recognize this one?

I'd second that. They are probably the hottest J pickups you can find without being custom made.
But yeah, the poles are kind of unique to those. If they measure 1/4", that's probably what you have. (1/4" -> 1/4 Pounder, get it?)

80s Fender MIJ PJ basses had large poles as well, but I never knew what they registered at on the multimeter...

I just took the cover off a Duncan SJB-3 Quarter Pounder, and it looks almost identical to the pickup in your photos. The sticker on the bottom is different, but my pickup is only a couple of years old. The sticker may have changed over the years.

Mine is a bridge model, with a DCR of 14.0K. On Duncan's site, the bridge SJB-3 is listed at 14.61K. Evidently, the DCR on those pickups varies somewhat; yours at 14.25K is certainly in the ballpark.
